申江路高架跨越上海磁浮示范运营线的综合监护技术

Comprehensive Technical Monitoring and Protection of Shenjiang Road Viaduct Crossing Shanghai Maglev Demonstration Line

上海磁浮示范运营线的安全保护区被定义为线路轨道外边线两侧各30 m范围。在磁浮保护区内进行施工作业时,应当通过涵盖施工对象及磁浮线路自身,贯穿施工前、施工期间和施工后的综合监护技术来控制其对磁浮结构及附属设施的影响。阐述了综合监护技术的主要工作内容,并以上海申江路高架跨越上海磁浮示范运营线为例,介绍了综合监护技术的工程实践过程,分析了几个关键技术及其在施工过程中的作用。研究结论可为类似工程提供参考。

The protection zone of Shanghai Maglev Demonstration Line is defined within a range of 30 m on both sides of the rail outer edge.During the construction work in the protection zone,outside influences on the maglev structure and ancillary facilities should be controlled through comprehensive technical monitoring and protection that cover the construction target and maglev track from the pre-construction to the post-construction.Main contents of the comprehensive technical monitoring and protection are introduced,and based on the Shenjiang Road Viaduct project that crosses the maglev line,the engineering practice is illustrated and some key links with their impacts on the engineering are analyzed.This research conclusion provides a reference for similar engineering projects in the future.
